Product Details

The ADRF6510 is a matched pair of fully differential low noise and low distortion programmable filters and variable gain amplifiers (VGAs). Each channel is capable of rejecting large out-of-band interferers while reliably boosting the wanted signal, thus reducing the bandwidth and resolution requirements on the analog-to-digital converters (ADCs). The excellent matching between channels and their high spurious-free dynamic range over all gain and bandwidth settings make the ADRF6510 ideal for quadrature-based (IQ) communication systems with dense constellations, multiple carriers, and nearby interferers.

The filters provide a six-pole Butterworth response with 0.5 dB corner frequencies programmable through the SPI port from 1 MHz to 30 MHz in 1 MHz steps. The preamplifier that precedes the filters offers a pin-programmable option of either 6 dB or 12 dB of gain. The preamplifier sets a differential input impedance of 400 Ω and has a common-mode voltage that defaults to 2.1 V but can be driven from 1.5 V to 2.5 V.

The variable gain amplifiers that follow the filters provide 50 dB of continuous gain control with a slope of 30 mV/dB. The output buffers provide a differential output impedance of 20 Ω that is capable of driving 1.5 V p-p into 1 kΩ loads. The output common-mode voltage defaults to VPS/2, but it can be programmed via the VOCM pin. The built-in dc offset correction loop can be disabled if dc-coupled operation is desired. The high-pass corner frequency is defined by external capacitors on the OFS1 and OFS2 pins.

The ADRF6510 operates from a 4.75 V to 5.25 V supply and consumes a maximum supply current of 258 mA when programmed to the highest bandwidth setting. When disabled, it consumes 2 mA. The ADRF6510 is fabricated in an advanced silicon-germanium BiCMOS process and is available in a 32-lead, exposed paddle LFCSP. Performance is specified over the −40°C to +85°C temperature range.

Evaluation Kits

Product Details

ADRF6510-EVALZ is a fully populated, 4-layer, FR4-based evaluation board designed to allow easy evaluation of all features of the ADRF6510. The evaluation board provides input and output SMA connections with single ended setups for both channels using baluns. There is an option of full differential signaling on the input and output at the card edge. Access to the +5 V/258 mA supply is achieved with clip leads to the VPS and COM testpoints; it has a range from +4.75 to +5.25 V. The evaluation board can be programmed through the USB port of a PC running Windows XP or Vista with Microsoft .NET Framework 3.5 installed. The required control software can be downloaded from www.analog.com.

ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.

Yet this device need to be put in layout and tested. but as per specs, its a device with great features and appropriate selection for IQ arm filters in QPSK Demodulator.
small query: can this be connected directly to single ended I/Q line.

Very useful for signal conditioning the Base band signal both in Up conversion or down conversion chain. This reduces the board space required for LPF and that too it is programmable.

This is an excellence product for IQ Down conversion Chain

Very useful for signal conditioning the Base band signal both in Up conversion or down conversion chain. This reduces the board space required for LPF and that too it is programmable.

Good feature, this product could be used in many application. However, the future TDD system would use wider baseband bandwidth such as 40MHz / 60 MHz, so this product maybe need expand its LPF band to meet this new requirement. Please take the Hittite HMC1023LP5E as a reference.
